The Veterinarian’s Oath does not specify companion animal welfare and companion animal suffering, but rather animal welfare and animal suffering.

Medical doctors take the Hippocratic Oath, which requires new physicians to swear to uphold specific ethical standards in their practice. Veterinarians also take an oath of ethics. Here it is, as stated on the website of the American Veterinary Medical Association:
Being admitted to the profession of veterinary medicine, I solemnly
swear to use my scientific knowledge and skills for the benefit of
society through the protection of animal health and welfare, the
prevention and relief of animal suffering, the conservation of
animal resources, the promotion of public health, and the
advancement of medical knowledge.
I will practice my profession conscientiously, with dignity, and in
keeping with the principles of veterinary medical ethics.
I accept as a lifelong obligation the continual improvement of my
professional knowledge and competence.
In this Open Letter to Veterinarians, I would like to address the
parts of this oath in which veterinarians solemnly swear they will
act via “the protection of animal health and welfare” and “the
prevention and relief of animal suffering”.
The Veterinarian’s Oath does not specify companion animal welfare
and companion animal suffering, but rather animal welfare and animal
suffering. This includes the protection and welfare of the
approximately 70 billion animals who are brutalized and murdered
each year by the factory farming industry—innocent, sentient,
intelligent animals who are born into suffering, stripped of their
dignity, ripped from their mothers and children and forced to give
their lives for human and pet food.
So my question to veterinarians is a simple one: If you have sworn
to protect all animals, then why aren’t you vegan?
Those of us who entrust you with the care of our companion animals
know that you are dedicated. You work long, hard hours and perform
arduous surgical procedures to save the lives of beloved family dogs
and cats.
And yet, many of you return home at the end of the day and consume
meals made up of other animal species—cows, pigs, lambs, chickens,
fish. You also recommend feeding these species to your companion
animal clients.
But these “food” animals who are treated as nothing more than
commodities also have families that love them. They also have lives
they want to live out in peace.
I’m sure you’re aware of the brutality that occurs inside of
slaughterhouses. The very word “slaughterhouse” reveals that these
are houses of horror. Yet this cruelest aspect of humanity is all
these animals will ever know, simply because of who they are.
In his 1975 book,
Animal Liberation, Peter Singer defines speciesism
as follows:
‘Speciesism‘ is the idea that being human is a good enough reason
for human animals to have greater moral rights than non-human
animals. … a prejudice or bias in favour of the interests of members
of one’s own species and against those of members of other species.
—Peter Singer
I would argue that humans also engage in another, equally insidious
and devastating form of speciesism—the bias that certain animal
species are superior to others and therefore have greater moral
rights. This form of speciesism occurs everyday in how society
treats animals it views as companions and those it views as nothing
more than commodities. It varies from culture to culture, showing
how arbitrary it is based upon a society’s collective social or
religious background.
Speciesism among different types of animals also pervades the
practices and homes of non-vegan veterinarians. It rears its ugly
head each time a bag or can of meat-based pet food is recommended to
a client or a veterinarian dines on a meal that was once a living
animal.
Speciesism within the veterinary community is particularly troubling
because veterinarians take an oath to protect all animals from harm
and suffering.

In my 10-plus years as a canine nutritionist with a master’s degree
in animal science, I have had the opportunity to work with clients
across the world. When I became vegan several years ago, I
transformed my business to formulate only plant-based diets for
dogs, a decision that I made after performing a great deal of
scientific research. Since that time, I have worked with many vegan
clients who want to provide their canine companions with optimum
nutrition that is also compassionate toward all beings. However,
these clients are afraid to even discuss feeding a plant-based diet
with their veterinarians for fear of backlash and ridicule.
That can change. There is a real opportunity for veterinarians to
take the lead here. You can guide your clients toward healthy,
balanced companion animal nutrition that respects the lives of all
animal species, including those not lucky enough to have been born
as “companion animals”.
In 2019, I created the
Plant-Powered Dog Food Summit, the first and
only online summit dedicated exclusively to plant-based canine
nutrition. This summit took almost a year to produce and involved
sending videographers around the world to interview the leading
vegan veterinarians and animal rights activists. These leaders
participated in the summit for the purpose of promoting education on
plant-based canine nutrition from both an ethical and health
perspective and to provide first-hand insight into the animal
welfare atrocities that occur within the animal agriculture
industry.
I would like to partner with you to help make our world a better
place for everyone. If you are a veterinarian who is open-minded to
learning more about plant-based companion animal nutrition, I have a
gift for you—free lifetime access to the Plant-Powered Dog Food
Summit. This includes more than 12 hours of science-based and
illuminating video interviews, as well as audio downloads and
written transcripts from these leading vegan veterinarians and
activists.
I promise you that it will be an eye-opening experience. All you
have to do is
contact me and I will grant you access.
According to the Vegan Calculator, the average vegan saves the life
of one farm animal per day. By going vegan and recommending
plant-based options to your clients, you can save tens of thousands
of animals. Imagine how gratifying that would be.
The planet is on the cusp of a new era and we all must decide which
way we want to go.
According to the Vegan Calculator, the estimated number of animals killed each year is:
As a society we must ask ourselves, “Do we want to continue down the
dark road of animal abuse and environmental devastation, or do we
want to move toward an enlightened world that nourishes everyone
with harm to no one?”
This question is even more important to you as a veterinarian.
You do not need to compromise the health and welfare of your
companion animal clients in order to uphold your Veterinarian’s Oath
to protect all animals from suffering and harm.
In the immortal words of Sting: “…nothing comes from violence and
nothing ever could.”
So, I ask you again: Why aren’t you vegan?
